Dental implants traditionally have a high success rate with numerous studies showing long-term success rates of over 95%. This is just one of the reasons they have been widely accepted as the best method for permanently replacing missing teeth. In fact, over-dentures, which are full dentures supported and stabilized by at least two dental implants, are now considered the standard of care by the American Dental Association (ADA) for people who have lost all of their teeth in one or both jaws. And while they have a high success rate, there are some factors that can compromise the success rates of implants.

These factors are generally divided into three categories: general health concerns, local factors, and maintenance issues.

General health concerns: Your general health, lifestyle, and habits can play a major role in the success of dental implants. For example, smoking, diabetes, osteoporosis (porous bone) or a compromised immune (resistance) system can all negatively impact implant healing and success. And if you have a history of radiation treatment to your jawbones, you are at a higher risk for complications.

Local factors: Some examples of local factors that can affect implant success include bone quality and quantity — having sufficient bone in the right place to accurately secure and locate the implants.

Maintenance issues: While implants are excellent high tech replacements for missing permanent teeth, they do require routine maintenance. This includes daily cleaning and continued professional care. Otherwise, implants are just like any other technically sophisticated devices — they may be susceptible to breakdown.
